Nature worship also called naturism or physiolatry is any of a variety of religious, spiritual and devotional practices that focus on the worship of the nature spirits considered to be behind the natural phenomena visible throughout nature. A nature deity can be in charge of nature, a place, a biotope, the biosphere, the cosmos, or the universe. Nature worship is often considered the primitive source of modern religious beliefs and can be found in pantheism, panentheism, deism, polytheism, animism, totemism, shamanism, some theism and paganism including Wicca. Common to most forms of nature worship is a spiritual focus on the individual's connection and influence on some aspects of the natural world and reverence towards it. Due to their admiration of nature, the works of Edmund Spenser, Anthony Ashley-Cooper and Carl Linnaeus were viewed as nature worship.
